CONSTRUCTION 0F YOSTS FOR FIELB-FENGES.

Specification of Letters Patent No. 22,712, dated January 25, 1859.

To atl whom it may concern.'

Be it known that l, Jol-IN Daowx, of Huron, in the county of rayne andState of New York, have invented a new and useful Improvement inPortable Fences; and do hereby declare that the following is a full andexact description thereof, reference being had to the accompanyingdrawings, making part of this specification, Figure l being a sideelevation of a portion of a fence constructed in my improved manner;Fig. 2, a top view thereof; Fig. 3, a transverse vertical sectionthereof inthe plane indicated by the line fr fr, Figs. l and Q.

Like letters designate corresponding parts in all the figures.

The sect-ions of the fence are formed of simple rails A, A, connectedtogether by upright pickets a, a, or in any convenient manner. The endsof each of the rails A, A, of adjacent sections, are halved together, asrepresented at b, h, so that they will present the uniform width ofsingle rails. The ends of the lower rails, where joined together, restin chairs B, B, of suitable length and size to serve as a rm foundationfor the fence. The notch or mortise c, (Fig. 3,) in the chair, whichreceives the ends of the lower rails, is made somewhat longer than thewidth of the oined rails, and may have a dovetail form, as shown in Fig.8; and the joined rails of the lower rails, which rest therein, aremade, in that case, of a corresponding form. A wedge (I, of suitableshape. driven into the notch, beside the lower rails, holds themsecurely in place. Small notches are made in the outer edges of theupper rails at their joints, substantially as represented at f, f, Fig.3. These notches are made of sutlicient width to admit the edges of thebraces C, C, therein, and said braces may have corresponding notches g,g, in their inner edges, to receive the rails. The braces project alittle distance above the rails, where they are connected together bymeans of a clamp 71, put over the ends of the braces, and fitting intosmall notches or holes z', lz', in the braces; or any other equivalentmeans of firmly holding the braces together may be employed. One of thebraces is secured firmly to the chair (as seen at 7c, 7a, Fig. 3,) so asto incline inward toward the fence. The other brace is then pressedinward and downward with some force, thereby lirmly tightening therails, and making the fence irin and steady. 1When it is brought to aproper position, its lower end is secured to the chair by a single nail,screw, or hook, Z, (Fig. The fence may be further tightened at any time,if it becomes unsteady, by removing tbe nail or screw Z, and pressingthe brace in more closely toward the center of the chair. It thusconstantly acts as a powerful lever to hold the fence firmly andclosely, while its fellow brace particularly sustains the fence in itsproper position.

The fence is readily taken down at any time by separating the leverbraces from the chairs. and removing the keys which conline the rails inthe chairs, when the parts scparate from one another. I

That claim as my invention and desire to secure by Letters Patent, is*

The arrangement of the braces C, C, one fixed and the other hinged orpivoted thereto, in combination with the rails A., A, and chair B,substantially as herein specified.

The above specification of my improved fence signed by me this 11th dayof October, 1858.
